CAR-FRAME.

Specification of Letters Patent.

Patented May 1, 1906.

To (1/! whom it may (JOTLOEZTVL:

Be it known that we, WVILLIAM H. EMERICK, residing in Osawatomie, in thecounty of Hiami, in the State of Kansas, and PETER AL- Uis'r, residingin Memphis, in the county of Shelby, in the State of Tennessee, citizensof the United States, have invented a new and useful Improvement inCar-Frames, of which the following is a specification.

Our invention relates to improvements in car-frames, and moreparticularly to means for removably connecting draft-timbers or otherparts to the center sills and other members of the carframework.

The object of our invention is to provide a simple, strong, efiicient,and durable means for removably connecting the draft-timbers to centersills and body-bolster or other parts of the car-framework.

Our invention consists in the means we employ to practically accomplishthis object or resultthat is to say, it consists, in connection with thecenter sills and body-bolster of a car, of draft-timbers removablyconnected both to the center sills and body-bolster, so that thedraft-timbers may be easily and quickly removed and replaced by new oneswhen broken without the necessity of unloading the car and whereby atthe same time the draft-timbers will be very strongly and firmlyanchored and secured in place and connected with both the center sillsandbolster.

Our invention further consists, in connection with the center sills,body-bolster, and draft-timbers, of dovetail connecting-plates securedto the draft-timbers and center sills and dovetail connecting-platessecured to the draft-timber and body-bolster, the connecting-platesbeing furnished with removable dovetail keys which when removed enablethe draft-timbers to be readily taken out and replaced.

Our invention further consists in the novel construction of parts anddevices and in the novel combinations of parts and devices herein shownand described.

In the accompanying drawings, forming a part of this specification,Figure 1 is a plan view of a portion of a car-frame embodying ourinvention. Fig. 2 is a vertical section on line 2 2 of Fig. 1. Fig. 3 isan enlarged detail vertical section on line 3 3 of Fig. 1. Fig. 4 is anenlarged detail horizontal section on the broken line 4 4 of Fig. 2.larged vertical section on the broken line 5 5 of Fig. 2. Fig. 6 is across-section on line 6 6 of Fig. 3, and Fig. 7 is a detail viewillustrating a modification in which a metal bolster is employed.

In the drawings, A A represent the draft or center sills of arailway-car, A the front or cross sill, and N the buffer-block.

B B are the removable drafttimbers to which the side plates orstop-castings are secured in the customary manner.

C is the body-bolster of the car body or frame.

To removably connect the draft-timbers B with the center sills A, thedraft-timbers are furnished with a series of dovetail connectingplatesD, rigidly secured thereto by bolts d,

. and they cooperate with corresponding dovetail connecting-plates D,rigidly and firmly secured to the center sills A and end sill A by bolts(1. The connecting-plates D and D are furnished on their meeting faceswith registering dovetail grooves (l to receive a removable doubledovetail key F, by which the connecting-plates D D are removably securedtogether. The connecting-plates D and D are further provided on theirmeeting faces with registering and interfitting recesses d and bosses orprojections d", which serve to additionally lock and secure theconnecting-plates against movement in the plane of their meeting faces.The heads (1 of the bolts (1 d fit in suitable countersinks or recessesformed in the connecting-plates D D, so that the heads of the bolts willnot interfere with the proper interengagement of the connectingplates.Two bolts are preferably employed for each of the connecting-plates D D,one on each side of the dovetail grooves and key F, and one of theconnecting-plates is preferably provided with two bosses or projectionscl, one on each side of the dovetail key, the same enteringcorresponding recesses in the other connecting-plate. The doubledovetail removable key F has one dovetail member f fitting in thedovetail groove of one connecting-plate and another dovetail member ffitting in the dovetail groove of the other connectingplate, so that thedovetail key securely locks the connecting-plates together. To look orsecure the dovetail key in place, it is provided with a Fig. 5 is an envbolt F, having a head f 2 and nut f and furnished with washers f 4 fprojecting over the marginal faces of the key and fitting against orengaging the upright faces of the connecting-plates D D, so that thebolt and its Washers thus lock the key in place while permitginlg itsready removal by first taking out the To removably connect thedraft-timbers B" B with the body-bolster C, the draft-timbers B areprovided at their rear ends with dovetail connecting-plates G, furnishedwith flanges or straps g and bolts g for connecting the same to thedraft-timbers and which cooperate with corresponding dovetail connectin-plates G, which are secured to the bodybdlster C by bolts 9 extendingthrough extension-flanges g of the plates G. The connecting-plates G Gare furnished on their meeting faces with dovetail grooves g grespectively, to receive the removable double dovetail key H, which isheld or locked in place by a bolt it, having heads h, nuts if, andwashers 72/ By this means we not only removably connect thedraft-timbers with the center sills, but also with the body-bolster, andat the same time provide an extremely strong, safe, and reliableconnection between the draftetimbers and the car-framework and enablethe draft-timbers to be quickly removed and replaced when broken or whendesired. While our connecting-plates are specially intended and designedfor cooperation with draft-timbers and center sills and body-bolster orother frame members of a car-body, the same may be used for removablyconnecting other parts and removably securing them together.

In the modification illustrated in Fig. 7 a metal bolster is employedand the connectingplate G is cast integral therewith.
